Starting the diagnostics causes the Dell logo screen to appear, followed by a
message indicating that the diagnostics is loading. Before the diagnostics
loads, a program tests the portion of main memory (RAM) required for loading
the diagnostics. If a main memory error is detected, a message appears on the
screen telling you which memory address failed.
If no errors are found in main memory, the diagnostics loads and the Diagnos-
tics Menu appears. This menu lets you choose the following options or exit to
the MS-DOS prompt:
Run Quick Tests — Runs selected tests from all test groups to quickly
locate the failure or to indicate where further testing may be needed to iso-
late a failure
Run All Tests — Runs all tests for a thorough test of the computer
Run Specific Tests — Tests a particular area or subsystem
